The invention provides an axle lifting device of a semitrailer, and relates to the technical field of semitrailer auxiliary tools. The axle lifting device of the semitrailer comprises three pairs of tires, rear axle shafts are arranged in the centers of the side walls of the three pairs of tires respectively, the other ends of the three rear axle shafts penetrate through the three pairs of tires respectively, rear suspensions are arranged in the centers of the two pairs of tires close to the rear side, the two ends of the three pairs of rear axle shafts are connected with the lower ends of the rear suspensions respectively, and the rear suspensions are connected with the rear suspension. Front axle plate springs are arranged on the upper sides of the two ends of the rear axle shaft on the side walls of the pair of tires close to the front side correspondingly, the lower ends of the two front axle plate springs are connected to the upper end of the rear axle shaft through front light axles correspondingly, and the upper ends of the two front light axles are connected with air bag lower fixing plates correspondingly. The upper ends of the two air bag lower fixing plates are connected with small air bags respectively. The tires are lifted after the axle is lifted during use, so that the tire wear is reduced, the tires are saved, and the fuel consumption is reduced.

    本发明提供一种半挂车的车桥升降装置,涉及半挂车辅助用具技术领域。该半挂车的车桥升降装置,包括三对轮胎,三对所述轮胎的侧壁中心处分别设置有后桥轴,三个所述后桥轴的另一端分别贯穿三对轮胎,靠后侧两个对所述轮胎的中心设置有后悬架,三对所述后桥轴的两端分别与后悬架的下端连接,靠前侧一对所述轮胎侧壁上后桥轴两端的上侧分别设置有前桥板簧,两个所述前桥板簧的下端分别通过前轻型桥连接在后桥轴的上端,两个所述前轻型桥的上端分别连接有气囊下固定板,两个所述气囊下固定板的上端分别连接有小气囊。通过在使用时提升桥后,轮胎抬起,减少轮胎磨损,节省轮胎和减少燃油消耗。
